Dear Colleagues,

The aim of this special issue is to provide medical professionals and scientists with new information on how trace elements, the environment, and especially certain nutrients can affect our life and health in the long term. Due to the complexity of the issue, it is necessary to approximate the professional nomenclature that will be used in individual publications. The presented topic is a great opportunity for research looking for alternative ways to explain the differences in the importance of the influence of various elements and nutrients on the body. The current scope of knowledge does not explain sufficient aspects of proper interaction and supplementation. Moreover, it is difficult provide their appropriate doses even with a varied and well-balanced diet. Proper diet and the content of individual elements is therefore an inseparable element treating patients with various disease states. Thus, the principles of a proper diet that can improve the effectiveness of treatment are very important. We invite you to contribute with research and review articles from all areas where scientists have proven the role of trace elements and nutrition for the benefit of society.
